Blocking device to access LAN

[xusco]

Hi there,

I have a probably easy question but I couldn’t find the answer in the forum.

I have a GT-AX6000 as main router and I would like to block one device to access other devices in my LAN:

• Solar inverter with IP 192.168.1.115. It needs internet access for monitoring but I don’t want it to communicate with my LAN as I considere it not trusted.
• The Home Assistant with IP 192.168.1.10 should access the inverter for monitoring as well and the inverter should replay the request from Home Assistant, so the inverter is not “completely” isolated.
• Synology NAS with IP 182.192.1.100 should also access the inverter for the same reason.

Is there a easy way to do it from the GUI? I tried Network Services Filter unsuccessfully. Can I do it with Skynet or another add on? Can I do it by adding a smart switch like Tplink SG108E?

I’m running Merlin version 3.0.0.4.388_4 and I can’t upgrade yet to the newest version with VLANs until I will make some changes in my infrastructure.

Thank you in advance,
